Offshoreonly.com - "Check Engine" on SC1000 tach

I have a SC1000 Smartcraft tach on my 2003 350 MPI Horizon. I've turned off all external sensors. The gauge says "check engine". I scan the motor with rinda. It says the only fault is the pitot sensor which I don't believe I have. I am not getting an alarm. If I get a fault such as low drive lube I get an alarm, it says fault and tells me what's wrong. In this case it just says check engine. Idk what else to do here. Is it that pitot sensor? Can I disable that with rinda?
